Add jmp_buf-macros.h for ColdFire.

This patch adds a jmp_buf-macros.h for ColdFire.  In conjunction with
a GCC patch to fix the libgcc build failure for ColdFire
<https://gcc.gnu.org/ml/gcc-patches/2018-01/msg02064.html> this
suffices to restore the build (tested with build-many-glibcs.py).  A
further patch will be needed for soft-float ColdFire (while the
function-calling ABI is the same for hard-float and soft-float
ColdFire, it turns out the glibc ABI is not - so another ColdFire
variant will be needed in build-many-glibcs.py), but I'll deal with
that separately.

Tested with build-many-glibcs.py (m68k-linux-gnu and
m68k-linux-gnu-coldfire).  (There's a localplt test failure for
coldfire; that's the only failure in the compilation part of the
testsuite.)
